If the property has been altered, extended or let out, full property rewires on a 1930s semi deserves more than a quick look. Roof-space access is straightforward, loft cabling is easy — but plasterboard-on-batten ceilings mean second-fix downlight work needs careful joist mapping. Priced against your 1930s semi's specific construction, not a template is the pivot point. Everything quoted after it follows from what the readings say, which is why the survey comes first at any NP23 address. The schedule of results records it either way.
Age alone does not condemn an installation. Plenty of older Ebbw Vale wiring tests perfectly well; some newer work does not. On valley terraces in Beaufort and Cwm it is worth ten minutes of anyone's time. Full property rewires on a 1930s semi is easy to get quoted badly and hard to get quoted honestly without looking at the installation first.
